In simple words: This code covers one bifocal lens that corrects both near and far vision. The lens has two sections, one for seeing things up close and one for seeing things far away. The strength of the lens is within a specific range.

This code covers a single, spherical bifocal lens with diopter measurements from plus 4.12 to plus 7.00 and minus 4.12 to minus 7.00. A spherical bifocal lens has a rounded surface separated into upper and lower sections to correct both nearsightedness and farsightedness. The lower half improves near vision, while the upper part improves distance vision.

Example 1: A patient with both nearsightedness and farsightedness requires bifocal lenses with a diopter measurement of +5.00 for the near vision correction and -4.50 for the distance vision correction. HCPCS code V2201 is applied for each lens., An elderly patient requires new bifocals. Their prescription indicates a need for a +6.00 diopter for near vision and a -5.00 diopter for distance vision. V2201 is billed for each lens provided., A patient's vision has changed, requiring stronger bifocals. Their new prescription specifies a -6.50 diopter for distance and a +4.25 diopter for near vision. HCPCS code V2201 is used for each lens.

The patient's eyeglass prescription specifying the diopter measurements for both near and distance vision should be documented in the medical record.
